...like ConvertKit? That's who powers the form that collects emails here. Just wanted to point out that this question is decidedly not hypothetical. Many websites use third-party services to administer their mailing lists. Now, this makes sense from a developer's perspective since we don't all want to be rewriting mailing list tools, but I'd wager many users aren't aware that their email address is being passed on to a third party. These are the sort of tradeoffs that we're now learning to address explicitly, as opposed to sweeping them under the rug in the name of "marketing". As much as it's a pain for me as a developer, I welcome it wholeheartedly as a user.
